Jock itch

Jock itch

Also known as tinea cruris, jock itch is a growth of fungus in the warm, moist area of the groin.

Fungal infections are named for the affected part of the body. Cruris is derived from the Latin word for leg, hence Tinea cruris, for the fungal rash affecting the area where the leg joins the pelvis. Fungi seem to thrive in dark moist places.

Jock itch has been found most often in males, especially those who wear athletic equipment and frequently use public showers and locker rooms. It is also thought that some fungal infections may be spread by towels that may be inadequately cleansed between gym/spa users, but this has not been clearly documented.

Usnea

Usnea

Usnea is a unique species of herb because it is created through a symbiotic relationship between lichens and algae. Symbiosis refers to the living together of two different organisms.

In the case of lichens, both the alga and the fungus benefit from the relationship. Other names for usnea include lichen moss and old man’s beard. Usnea can be found in forests in northern North America and are also found in Europe.

Some usnea are able to keep growing even after being broken off from the parent organism. Usnea are very sensitive to the air quality and may be killed by absorbing pollutants. In fact, usnea are used as indicators of regional pollution levels.
